Honeywell TPE331 To Power Kestrel T-prop Single
Kestrel Aircraft selected Honeywell’s TPE331-14GR to power its all-composite single-engine turboprop.

Kestrel Aircraft selected Honeywell’s TPE331-14GR to power its all-composite single-engine turboprop. The Brunswick, Maine-based company was founded by Alan Klapmeier, co-founder of Cirrus Aircraft, to bring the former Farnborough Aircraft F1 Kestrel turboprop to market. The TPE331-14GR, rated at 1,759 thermodynamic horsepower, will be flat-rated to 1,000 shp, according to Kestrel, “to allow for better high-altitude, high-temperature performance.” Honeywell will certify a version of the -14GR for the Kestrel, with external changes to fit the aerodynamic shape, including relocation of accessories.
